Grain prices were mixed but mostly higher on Tuesday as traders resumed a holiday-shortened week, with corn prices showing the most upside due to concerns about U.S. crop quality and production potential. Wheat prices also made moderate inroads, but soybeans failed to follow suit due to improved exchange rates in Argentina. Some parts of the Northern Plains and upper Midwest will see rainfall in the coming days, but large portions of the Corn Belt will not. The Dow sank 160 points lower in afternoon trading due to concerns about interest rates moving aggressively higher. Corn export inspections for the week ending September 1 declined moderately, and soybean export inspections moved moderately higher. Wheat export inspections faded moderately, and the European Union's 2022/23 soft wheat exports reached 228.2 million bushels through September 3, slightly above last year’s pace.
